Weaving finishing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weaving technologies are limited to finishing the lateral edges of woven products uniformly and linearly, neglecting the interior portions and requiring post-processing pattern cutting for non-linear shapes.
Innovation Solution
A loom with dynamically positioned finishing devices that can independently finish one side of a woven product differently from the other side, allowing for non-linear shapes and enabling interior finishing, creating apertures, pockets, and tunnels during the weaving process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional linear edge finishing is used, then uniform width is maintained, but non-linear shapes require post-processing pattern cutting
Solution Approach 1:
The finishing device is made dynamically positionable along the warp threads, allowing it to move laterally and finish edges in non-linear patterns during the weaving process itself, eliminating the need for post-processing pattern cutting while maintaining edge quality
Solution Approach 2:
The edge finishing operation is performed preliminarily during the weaving process rather than as a subsequent operation. The finishing device completes the edge shaping while the fabric is being formed, preventing the need for later pattern cutting and post-processing steps
2Device complexity
If edge finishing is limited to lateral margins, then the process is simple, but interior portions cannot be finished
Solution Approach 1:
The finishing device is designed with universal applicability to perform both lateral edge finishing and interior portion finishing. By making the device laterally positionable along the warp threads, it can operate at any position across the fabric width, enabling it to finish both margins and interior portions with the same mechanism
Solution Approach 2:
The finishing device incorporates dynamic positioning capabilities that allow it to move laterally along the warp threads and adjust its position during the weaving process. This dynamic movement enables the device to access both lateral margins and interior portions of the fabric, expanding its functionality beyond static edge finishing
3Productivity
If both sides of the woven product are finished simultaneously, then the process is efficient, but independent side finishing is not possible
Solution Approach 1:
The finishing system is segmented into independently controllable finishing devices, each capable of operating on one side of the fabric. This segmentation allows each device to be controlled independently, enabling different finishing patterns and parameters to be applied to each side simultaneously while maintaining overall process efficiency
Solution Approach 2:
The finishing devices incorporate dynamic positioning and independent control systems that allow each side to be finished according to different requirements. The devices can move independently along the warp threads and apply finishing operations with different parameters, patterns, and timing on each side of the fabric simultaneously

AI summary
A dynamic finishing device that is able to finish one side of a product independently of a second side of the product while the product is being woven is provided. The sides may be finished in a non-linear fashion by the dynamic finishing device. Additionally, one or more finishing devices can be dynamically positioned in an interior portion of the woven product as it is being woven. Once positioned, the finishing devices may create apertures, pockets, and/or tunnels in the woven product and finish the edges of these creations. Finishing in the interior portions of the woven product occurs in the direction of the warp and in the direction of the weft.
